Hello Kavindra,

There is a bug report about improving the Qt CMake documentation, where we are collecting ideas: https://bugreports.qt.io/browse/QTBUG-72159

Please add your questions and concerns there.

That's good to hear. I understand that there will be two levels of documentation:

- CMake itself on their side
- Qt's CMake related content; like the macros you mention

Regarding the possibly-internal bits, I would vote for having them documented still -- even if there's a note or a disclaimer explaining their status. This is a good way for your team to maintain the messaging; instead of having random blog posts circulating online about people's experiments on these internal macros. Those would then deviate from the official messaging. Additionally, I believe some of my colleagues, who are module maintainers outside of The Qt Company, could use this information.

Sure, I'll try to help with reviews when I have some time.

Thanks for your response,

    CMake has quite extensive documentation: https://cmake.org/cmake/help/latest/

    I think this is the case 😊 We're also gradually improving the documentation of CMake macros that Qt provides, see https://codereview.qt-project.org/q/topic:%22cmake_transition%22 (reviews welcome btw).

    Now there will still be CMake macros & functions that are only used when building Qt itself (-> are internal). I don't think it makes sense yet to document them, because they're still in flux. But once things stabilize it would be IMO a good move to at least provide overview documentation.
